BOILER-CLEANING DEVICE.

Application filed October 23, 1894. Serial No. 526,743. at. model.)

To aZZ whom it may concern:

Be it known that I, DAVID WAIGHT, a citizen of the United States,residingat Beaver Falls, in the county of Beaver and State ofPennsylvania, have invented certain new and useful Improvements inBoiler-Cleaning Devices; and I do hereby declare the following manner ofattaching or holding the said skimmer in place, so that its heightwithin the boiler may be conveniently adjusted to the normalWater-level, and also that it may not be injuriously shaken about orbroken from its fastenings by agitation due to the foaming of the boileIn the accompanying drawings, wherein like letters represent like parts,Figure 1 is a ront interior elevation of the boiler with the skimmer inplace; Fig. 2, aninterior section view, and Fig. 3 a detached top planof the skimmer, the better to show its outline form. Fig. 4 is avertical longitudinal section show in g the vertical and the horizontaladj ustability of the connection between the skimmer and the pipe toconduct turbid water out of the boiler; and'Fig. 5, an elevation of thesame with the pipe in section, showing particularly the verticaladjustability of the said connection.

A is the boiler; B, a yoke depending perpendicularly within the samefrom the shell of the boiler; O, the skimmer, and D the pipe incommunication with the skimmer to conduct the turbid water out throughthe back wall of the boiler to the settling-chamber. The yoke is rigidlysuspended from the shell of the boiler in any suitable manner that willpermit said yoke to be raised or lowered within the boiler for purposesof adj ustment-as, for instance, by sorew-stem and nut outside theThecausing the wall to bearagainstthe yoke, and v the skimmer is thusfastened in place.

It will be seen from Fig. 1 that if the floor of the skimmer should beout of level the defeet might be remedied by giving the yoke B a partialturn in its socket after loosening its feet from their screw-nuts, thusraising one side of the skimmer and depressing the other within thelimits of the inclined slots in the skimmer sides till a level floorshould be gained.

To permit of the adjustment just described the. side walls of theskimmer form a regular incline from front to rear of the skimmer, sothat they are higher at the rear than at the 'front. The plane of theskimmer is triangular, as customary with cleaners of this class. Anorifice d, in the back wall of the skimmer, receives the mouth of theconduit-pipe which is to remove the impurities from the boiler. Thisconnection between skimmer and conduit-pipe through said orifice is tobe carried out in any suitable and familiar manner that will permit theskimmer to be moved forward or backward or raised or lowered in itsadjustment to the water-level. As already indicated, this adjustment ismainly effected through moving the skimmer by means of its pair of longsloping slots upon the feet of the yoke, for, as will be seen from thedrawings, the farther the skimmer is moved'forward the lower it willdescend to reach the water-level.

By referring to Fig. 2 it will readily be seen how the delivery-pipe maybe fitted to the horizontal and vertical adjustments of the skimmer. Inits passage through the boiler-shell and through the back wall of theskimmer the pipe is in each case held by a pair of oppositely-placedcollar-nuts, arranged to bear toward each other from and against theopposite surfaces of boiler-shell and skimmer-wall, and as these twopairs of collars are movable along the surface of the pipe it is evidentthat the pipe can advance or recede within the boiler or the skimmer, orboth, and so be accommodated to the horizontal adj ustment of theskimmer. justment to adapt it to a high or low water level in theboiler, the orifice in the back of the skimmer being verticallyelongated to the comparatively slight extent needed to meet thehabitually small diiference between waterlevels in the boiler, itfollows that the delivery-pipe may be set nearer the top or the bot tomof the orifice, as occasion may require, and all that part of theorifice notfilled by the pipe will be closed by the clamping of thecollar-nuts. The delivery-pipe and its connections with boiler orskimmer are no part of the invention. The adjustments of the skimmer aremanual, not automatic, and are made within narrow space-limits, and thecon neoting of the delivery-pipe to the skimmer, so as not to interferewith the adjustability of the skimmer within its necessary limits, is amere piece of ordinary work for a steam or As to its verticalad boilerfitter or a machinist. For these reasons it is not deemed necessary tomore particularly describe or illustrate the delivery-pipe connections.

The operation of a boiler-skimmer of this kind is so well known tosteam-engineers, firemen, and fitters that it need not be described.

I claim- The combination of the yoke rigidly supported Within and by asteam boiler, and having the pair of outwardly turned feet, with thetriangular based skimmer having the inclined side walls and, in thosewalls, the inclinedslots adapted to engage the feet of the yokeaforesaid; the said skimmer having also the orifice in its back wall incommunication with the ordinary outlet pipe of such a cleaner, and thewhole constructed and arranged as and for the purposes hereinbeforedescribed.

In testimony whereof I aflix my signature in presence of two witnesses.
